ADJUSTMENT PROCEDURESTo avoid possible exposure to microwave energyleakage, adjust the door latches and interlockswitches, using the following procedure.The Interlock Monitor and Secondary Interlock Switchact as the final safety switch protecting the user frommicrowave energy. The terminals between “COM” and“NC” of the Interlock Monitor must close when the dooris opened. After adjusting the Interlock Monitor Switch,make sure that it is correctly connected.Mounting of the primary/monitor/secondary switches tothe latch board.CHECK THE DOOR LATCH AND SWITCHCLOSING.NOTE:The outer cover of the microwave oven isremoved.(1) Set the microwave oven on its side so that you cansee the latch board and the switches, as shown inFigure 24-a.(2) Close the door tightly and check gaps A and B tobe sure they are no more than 1/64" (0.5 mm).See Figure 23 for close-up view of gaps A and B(door latches). If all gaps are less than 1/64"(0.5 mm), adjustment of the latch board may notbe necessary. Go to Steps 5 and 6 to check thesequence of the switches.NOTE:To correct sequence of the Primary InterlockSwitch, Secondary Interlock Switch and theInterlock Monitor Switch is very important.If any gap is larger than 1/64" (0.5 mm), you willneed to adjust the latch board”. Go to step 3and follow all steps in order.ADJUST THE LATCH AND SWITCH CLOSING(3) Loosen the two screws holding the plastic latchboard as shown.(4) With the oven door closed tightly, move the latchboard upward toward the top of the oven and/oraway from the door latch until the gaps are lessthan 1/64" (0.5 mm).Hold the latch board tightly in this position until youcheck the sequence of the switches in steps 5and 6.7-12INTERLOCK SYSTEMINTERLOCK MECHANISMThe door lock mechanism is a device which has been specially designed to eliminate completely microwaveactivity when the door is opened during cooking and thus to prevent the danger resulting from the microwaveleakage.LATCHLATCH BOARD0-1/64"0-1/64"Latch BoardPrimaryInterlock SwitchMonitor SwitchInterlockSecondaryInterlock SwitchFigure 24-aFigure 24-b
